Adjuvant chemotherapy and outcomes in patients with nodal and resection margin-negative pancreatic ductal adenocarcinoma: A systematic review and meta-analysis.

Adjuvant chemotherapy (AC) following pancreatic carcinoma (PC) resection improves overall survival (OS). A systematic review identified 10 phase-2/3 studies investigating AC in 3644 patients looking at the influence of nodal and resection status. AC significantly improved disease free survival, OS and 5-year odds of death risk. There was greater survival benefit in patients PS 0 and with body/tail tumors. There was a nonsignificant effect in N -  /N  + patients on OS and no difference between R0/R1 patients.
